Betreff: LF: 1476 kHz AM
After the sad demise of all LW and MW broadcasts in Germany, a handful of p= ioneers came up who are operating legal low-powered medium wave stations in= the context of a radio museum or for educational purposes. One o= f them is Ralph (DL2NDO, one of the participants in the legendary Donebach 137 kHz activation in 2002). He has obtaine= d a transmitting license for 1476 kHz (former frequency of Vienna Bisamberg= ), built a 3 Watt AM transmitter, and with the help of a small te= am raised a quarterwave antenna on the Fraunhofer premises south of Erlangen (JN59MN21HF).

Yesterday they got on air for the first time, running a preliminary test tr= ansmission consisting of switched 1000 Hz beeps (one second on, one second = off, audio frequency locked to the RF carrier). This pattern will be c= ontinued for a few days, before they will eventually.take over the audio from the local DAB student radio = "funklust".

The current test pattern is relatively easy to make out in the noise so it = may be a good chance for some DX detections.  At night we've actually = heard the beeps on Twente SDR and a couple of German Kiwi-SDRs. B= ut I guess using narrowband signal processing techniques, the carrier and coherent tones could make it much further. The carrier fre= quency is derived from an OCXO and is currently at 1476000.411 Hz.

Will anyone in the group take the challenge?
